1b all. whom 'it may concern:

Be itknown that I, W'Aaxra B. Cooke, a citizen of the United States, residing in Jenkintown, Pennsylvania, have invented certain Improvements in Rail-Anchors, of which the followinlf is a specification.

One object of this invention is to proyide means for preventing the longitudinal creeping of rails of a railway track.

A further object of the invention is to so construct the device thatit can be clamped to the rail in the proper position against one side of a tie and any movement ot' the rail will cause the clamp to bite into the rail.

In the accompanying draWing:--I"igure l, is a side view of sutiicient ot' a railway track to illustrate my invention; Fie. 2, is a sectional view on the line 2 2, ig. l; Fig. 3, is a perspective view of one section ofthe clamp; Figs. 4 and 5, are views illustratino' modifications of the invention; and Fig. 6, is a perspective view of one section of the clamp with the sei-rations only on the upper edge.

A is the rail mounted on the ties B in the usual manner, D is the clamp made in two Asections D', one preferably made identical with the other, one being mounted on one side of the rail and the other on the other side. The portion (Z of each section lits between the under side of the head aof the rail and the base ilange av, and the upper edge of this portion is serrated, or toothed. as illustrated at, d', to bite into the head of the rail, and the lower edge is toothed, as shown at d", to bite into the upper edge of the base flange of the rail. Each seetion tits snugly around the base Hangc ot' the rail and has depending portions e through which pass one or more bolts f which eontine the sections to the rail.

The clamp is adjusted on the rail in contact with a tie B, as illustrated in Fig. T. Any movement of the rail 'in the direction of the arrow, due to creeping, will tend to tilt. the clamp id the serrated portions of the clamp wil )iteinto the under surface of the head and tlrfupper surface of the In Fig. 4, I have shown a diterent form of clamp, in which a securing bolt f" passes through an opening in the web of the rail, and either the web or the clamp is slotted to allow for adjustment. Each inember of the clamp has a depending portion c in this instance, which bears against the side, of the tie B.

In Fig. 5, I have shown a modification, in which two bolts f, f are used, one passing under the rail and the other thrrigh the web of the rail to secure the sections DA of the clamp to the rail. In this instau'ie I provide a separate serrated plate als the serrations bearing against. the under side ot' the head of the rail, so that any longitudinal movement of the head of the rail in one direction will cause the clamp to tilt, thereby making its sei-rations bite into the rail. The clamp may also be provided with fixed or detachable .serrated sections adapt. 7.5

ed to bite upon the iiange of the rail, as in the other figures, if desired.

I claim p 1. The combination of a rail. a tie, with a clamp secured to the rail and adapted to bear against the tie, the upper edge of the clamp having sei-rations adapted to tit. against the under surface of the head of the rail, so that on 'the movement of the rail i transversely of the tie the clamp will be tilted by abutting against the tie and its serrated surface caused to bite int-o the head of the rail.

2. The combination of a rail, a tie, with a clamp secured to the rail, said clamp being made in two sections, one of said sections having a por'ion litting between the head of the rail and the base flange thereof, and the upper and lower :surfaces of said portion being serrated so as to bite into the under surface of the head and the upper surface of theA flange when the clamp is tilted due to its abutting against the tie by reason of the -rail moving transversely of said tie.

3. The combination of a rail, a tie, a clamp made in two sections, each section having a portion fitting between the base flange and the head of the rail. said portions having serratious adapted to bite into the base flange and into the head of the rail when the cla-.np is tilted owing to its abutting against the tie as a. resultof a longitudinal movement'of the rail, with transverse vlooltsf ,securing the twosoctions' together.

4. The combination of a tie, a chimp inode in two sections each having u portion shaped to fit between the hase flange of thqrail and the head :1nd having upper und lower Serruted surfaces placed to bite into the upper surface of the basctlange and the lower surface of thevhead of the ruil, when the clamp is tilted due to its Contact with the tie as a result of a longitudinal movement of the rail, the sections'of the. clamp extending under the rail and' having depending portions, with a bolt passing through the depending portions and,confiningthevchnnpQI to the mii. A K

5 ik rml anchor made 1n two Sections, one

section having sharp teeth on the iop sm'- face of its up Jer edge pinned to bito into tin` under side ot the head of :a ruil win-n the. section' is tilted, the said section conforming to the shape of the rml.

A 'ruil anchor :nude in two section, euch having two toothed surfaces, one :nn-- face being placed to bite into the mnh-r ridi; of the head of a rail und the other section being in Vposition te bite info the bmw flange of the ruil when the clump is tilted.

In testimony whereof, l hin-'e signed my name to this specification, in the profounof two subscribing witnesses. A WARNER B. COOKE.l Witnesses: j l
